Which planet in the solar system may once have had a ring like Saturn? Surprisingly but it’s Earth that may have sported a Saturn-like ring system 466 million years ago, after it captured and wrecked a passing asteroid, a new study suggests. The debris ring, which likely lasted tens of millions of years, may have led to global cooling and even contributed to the coldest period on Earth in the past 500 million years. Using computer models of how our planet's tectonic plates moved in the past, scientists analyzed 21 crater sites around the world (across modern Australia, China, Europe, India, North America and Russia) that researchers suspect were all created by falling debris from a large asteroid between 488 million and 443 million years ago, an era in Earth's history known as the Ordovician during which our planet witnessed dramatically increased asteroid impacts. ℹ️Saturn isn’t the only planet with rings. Jupiter, Neptune and Uranus have less obvious rings, too. Subscribe- t.me/askmenow
